L2024-01R is an Escherichia coli­derived recombinant protein corresponding to full­length mature rat leukemia inhibitory factor (LIF), a secreted peptide with the capability to induce terminal differentiation in leukemic cells. It is expressed as a GST­fusion protein using a pGEX expression system, cleaved from GST via thrombin and purified by ion exchange chromatography.

Aiquot and store undiluted at -20°C. Aliquots are stable for at least 6 months at -20°C. Avoid repeated freezing and thawing as this may denature the protein. Should this product contain a precipitate we recommend microcentrifugation before use. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
